does this still hold after support item is fully completed? in low elo, support mages farm so much, and this would really hurt
Tribute/Spoils go away when the support item is completed so the answer can be yes or no depending on your perspective
::edit:: To signal boost below conversations, the penalty doesn't go away anymore, even when the item is fully upgraded. For added context, this is a harsher rule than with the old items, since mage supports in particular turned into mid-lane mages with 4 wards after finishing Eye of the Watchers. Especially with the 1400 gold free gold supports are getting, we're now saying "you can have either regular farm gold [by selling the item] or the Warding passive, but not both."
